Standard gas springs and lockable gas springs may look similar from the outside, but they are used for different functions. Understanding the difference is important for buyers who want the right motion control behavior in their product. A standard gas spring is mainly used to support lifting, opening, and holding tasks. A lockable gas spring, by contrast, is designed to allow controlled positioning and holding at selected points during movement.
A standard gas spring provides extension force and support through its internal gas pressure. It is suitable for applications such as hoods, tailgates, cabinet doors, machine covers, and storage beds, where the goal is to reduce lifting effort and support a moving component in an open or partially open state. In these applications, the gas spring mainly assists motion and creates a smoother operating feel.
A lockable gas spring adds a control function. It is used when the application needs to stop and hold the moving part at one or more positions. Typical examples include medical equipment adjustment, treatment tables, hospital beds, ergonomic seating, and other structures where the user may need to select a comfortable or practical angle. This type of product helps create adjustable positioning rather than simple lift support alone.
From a buyer’s perspective, the choice depends on product function. If the moving part only needs lifting assistance and stable support, a standard gas spring is often the right option. If the part needs to be adjusted, held, or repositioned during use, a lockable gas spring may be necessary. The decision should be based on the real user interaction and motion requirement rather than appearance.
It is also important to consider complexity and cost. A standard gas spring is usually the more direct and economical solution when positioning control is not required. A lockable gas spring offers more functionality but should be selected only when the application truly benefits from controlled adjustment. Otherwise, the product may be over-specified.
If you are not sure which type your product needs, describe how the moving part should behave: whether it only needs lifting assistance, or whether the user must stop and hold it at different positions. With that information, a standard or lockable gas spring can be recommended before samples are made, which avoids unsuitable samples and shortens development time.
